Embodiment

[0021] Embodiment: Take the masson pine as an example:

[0022] (1). The pine needles and pine bark of the collected pine trees are shortened and cleaned;

[0023] (2). Put the raw materials into the alcohol extraction tank, add 75% ethanol of 5 times the amount, boil for 1 hour, the vapor pressure is 0.5MPa, and the ethanol is refluxed;

[0024] (3). Filtrate after the first alcohol extraction to obtain filtrate and filter residue respectively. The filtrate recovers ethanol through a decompression concentration tank until the recovery of ethanol <60% stops recovery, and the filtrate continues to concentrate to obtain a concentrated solution 1;

[0025] (4). Add 5 times the amount of 75% ethanol to the filter residue for the second time, boil for 1 hour, the steam pressure is 0.5 MPa, and the ethanol is refluxed until the recovered ethanol is <60%, stop the recovery, filter, and obtain filtrate 2 and filter residue respectively;

[0026] (5). Add 8 times the amount of water ...

Abstract

Disclosed is a fore-anthocyanin which is extracted from pine needle and pine peels through the steps of collecting pine needle and pine peel, bobbing and sorting, charging the raw material into alcohol extraction tank, obtaining concentrated liquid through filtering after first alcohol extraction, secondary filtering of filtering deposit, obtaining filter liquor and filtering deposit respectively, charging 8 times of water into the filtering deposit, obtaining filter liquor and filtering deposit respectively through filtering, abandoning the filtering deposit, concentrating the concrete, storing the concrete at 1-5 deg. C, finally spray drying the concrete. The invention can be applied for substituting antibiotic medicines.

Description

technical field [0001] The invention relates to a proanthocyanidin component, which can be used as a feed additive raw material and belongs to the feed additive [0002] technology field. Background technique [0003] In order to promote the rapid growth of animals, feed additives are widely used in the breeding industry, and antibiotics in feed additives will lead to the decline of animal immune function, weakening of small intestine absorption function and intestinal flora imbalance. The most harmful to humans is the animal food source products. The drug residues in the human body are too high, resulting in the generation and transfer of drug-resistant bacteria, so once humans are infected by pathogenic bacteria containing drug-resistant factors, commonly used antibiotics will lose their normal therapeutic effect. [0004] So far, the recognized antibiotic substitutes mainly fall into three categories: enzyme preparations, probiotics and natural product extracts. Natural ...
